We compared two statistical methodologies applied to genetic and genomic analyses of categorical traits. The first one consists of a Bayesian approach to the Bayesian Linear Mixed Model (BLMM), which addresses the statistical problems of genomic prediction. The second methodology, called Bayesian Generalized Linear Mixed Model (BGLMM) is similar, but it is used ... more
Tomatoes are an important crop in Brazil. In advanced stages of breeding programs, the capacity to select or reject tomato lines becomes complex. We selected tomato lines comparing different selection strategies. We evaluated 115 advanced tomato lines from the Tomato Germplasm bank of the Federal University of Uberlândia. The following characteristics were ... more
A possible strategy to increase grain yield in common beans (Phaseolus vulgaris) is to obtain lines with earlier flowering and a longer grain filling period, associated with a higher dry matter accumulation rate. We examined the genetic control of these traits to investigate whether it is possible to select lines with earlier flowering, a longer period of ... more
The umbu tree (Spondias tuberosa) is endemic to the Brazilian semiarid region. This species is not cultivated and commercialized fruits are a result of extrativism; consequently little has been done to develop new and more productive cultivars. Hybrids of different accessions are a result of natural open pollination, so identifying putative male parents ... more
The umbu tree (Spondias tuberosa) is one of the best known plants of the Brazilian semi-arid region; it has great potential for the fruit market due to excellent consumer acceptance. This tree is not presently cultivated; fruit commercialization is based on extrativism. Consequently, there has been little research on the genetics of this species. Our ... more
Orange rust, caused by the fungus Puccinia kuehnii, results in high productivity losses in sugarcane. Selection of resistant genotypes is one of the aims of sugarcane breeding programs. Phenotypic and molecular characterization of the parents of such crosses is essential to obtain superior varieties. We evaluated the reaction to orange rust in the field, ... more
Wheat is considered a basic cereal for civilization with great economic importance for world agriculture. Currently, wheat is planted in the south, southeast and midwest regions of Brazil. Brazilian consumption of wheat will grow in the coming years due to population increase, which will require developing new cultivars for non-tradtional regions. We investigated ... more
Morphological or isozyme markers related to physiological maturation and deteriorative processes are important in the evaluation of seed quality. Two experiments were conducted to examine the possibility of using isozymes as indicators of quality in tobacco seed lots and fruit appearance as an indicator of physiological maturity in tobacco cultivars, based on the physiological and biochemical ... more
